Separation of feldspar from quartz using EDTA as modifier

1999-11-1  Separation of feldspar from quartz using EDTA as modifier 1395 The froth fractions and unfloated residue were dried and weighed. The percentage of the available mineral in the system reporting into the froth phase was used as a measure of floatability; it is termed the Microflot Floatability

Separation of feldspar from quartz: Mechanism of mixed

2002-8-1  Using pure albite and quartz minerals, the separation of albite from quartz using mixed cationic/anionic reagent schemes is assessed through Hallimond flotation, zeta potential and diffuse reflectance FTIR studies. The reagent schemes are tested in bench-scale flotation for the separation of albite from Greek Stefania feldspar ore.

A SIMPLE METHOD TO SEPARATE QUARTZ AND

2008-5-21  Grinding together quartz and feldspar grains in an agate mortar results in crushing the feldspar fraction due to its smaller hardness. Later sieving of the grinded mixture enables simple separation of both fractions. Then it is possible to save the feldspar fraction for later analyses instead of losing it as it occurs when using acid etching. Also,
